Description
Technical Field
The invention relates to the technical field of soilless culture of red kiwi fruits, in particular to a root-limiting soilless culture technology of red kiwi fruits.
Background
The kiwi fruit is a wild vine plant, and in the varieties of the kiwi fruit, the red heart kiwi fruit is a new variety which is cultured by combining with wild resources, has better taste, higher yield, richer nutritional value of fruits, medicinal value, rich vitamin C, vitamin A, various amino acids and mineral substances, is very beneficial to the development of human brain, and is called as the king of vitamin C and the king of fruits.
The red-heart kiwi fruits are large in leaves and rapid in growth, and are female and male, the kiwi fruits can bear fruits after being planted for 3 years generally, the kiwi fruits usually grow in slightly acidic and humid soil, the root system is fleshy root, the respiration effect is strong, the soil needs to be guaranteed to have good air permeability and oxygen content, the sandy soil with rich organic matters is guaranteed, and the PH is preferably 5.5-7.
However, present red heart kiwi fruit mainly relies on the soil resources in place to cultivate when planting, the planting scope that leads to the kiwi fruit is comparatively limited, simultaneously in the planting process owing to there is the germ in planting soil, the seedling that leads to the kiwi fruit is attacked disease easily when planting, and then greatly reduced the survival rate of kiwi fruit seedling, the cultivation cost of kiwi fruit has been increased, secondly, only rely on the soil resources in place to plant the kiwi fruit, lead to the kiwi fruit to all can't obtain accurate the accuse in the nutrition replenishment in different growth periods, simultaneously owing to the existence of planting ground pest damage, the kiwi fruit output after finally can making the maturity is lower.
Disclosure of Invention
The invention aims to solve the problems and provide a root-limiting soilless culture technology for red-heart kiwi fruits.
The invention realizes the purpose through the following technical scheme:
a root-limiting soilless culture technology for red kiwi fruits comprises the following steps:
step 1: the mixture ratio of the matrix is as follows: firstly, uniformly mixing imported seedling raising matrix, washed coconut coir and river sand according to the proportion of 1:3:1, then uniformly pouring carbendazim solution onto the mixed seedling raising matrix according to the proportion of 1:5, and stirring the seedling raising matrix again to finally pile the seedling raising matrix;
and 2, step: matrix disinfection: uniformly coating a layer of perlite with the thickness of 1.5cm on the mixed substrate to reduce water evaporation, uniformly punching two rows of holes on the upper part of the substrate stack by using a wood stick, sealing the holes by using a film, and fumigating for 10 days in the sun;
and step 3: selecting a container: a root controller with the height of 50CM is selected, the fixing position of the root controller is designed into a circular container with the diameter of 1 meter, and a gardening ground cloth is preferably paved in the container placing area, so that the appearance is attractive, and the workload of later-stage weeding is reduced;
and 4, step 4: designing a shed frame: setting the interval of each shed frame to be 4 meters, fixing 4 square steel upright columns with the height of 2 meters as supports, arranging threading holes at the upper parts, and pulling steel wires to fix the steel wires into a net shape so that vines grow along the steel wires;
and 5: planting management: in order to ensure the planting quality, the planting time of the kiwi fruits is generally after leaf falling and before sprouting, meanwhile, the grafted parts cannot be buried in the soil, when the kiwi fruits are planted, large seedlings are preferentially planted, and high-quality seedlings with strong plants and intact roots are selected; when the fruit trees are planted, the proportion of male and female plants of the fruit trees is also considered, and the preparation proportion of the male and female plants is recommended to be 5: 1;
step 6: trimming management: the kiwi fruit branches are generally trimmed by selecting long tips, only 1 main vine is reserved, the branches are fixed by a branch binding device, so that the branches climb to a shed frame, and then lateral branches are configured; generally, in the 1 st year of field planting, when a new shoot grows to 10cm, 2 main vines are selected as trunks, then pinching is carried out, then when the new shoot grows to about 30cm, 1 main vine is selected as a trunk again, and other auxiliary shoots are erased; if the young sprout is weak in growth, the young sprout is cut short in time to promote the young sprout to be updated, so that a thick young sprout is grown, and the pruning time is generally carried out in winter (12 months, late ten days-1 month, middle ten days);
and 7: and (3) fertilizer and water management: only using the formula A, the special formula B, the special formula C and the special formula D respectively at different growth periods of the kiwi fruit to ensure the normal growth of the kiwi fruit and increase the yield;
and step 8: and (3) pest control: firstly, cleaning a greenhouse, collecting branches and tendrils and overground residue and fallen leaves after pruning, and intensively destroying the branches and tendrils and the overground residue and fallen leaves; secondly, the trunk is whited, copper sulfate, lime, salt and water are prepared into Bordeaux mixture according to the proportion of 1.0: 5.0: 0.1: 10.0 to carry out the trunk whitewashing; thirdly, spraying 3-5 degrees barium lime sulphur, or spraying crystal lime sulphur mixed with 10-15 times of water; fourthly, the planting ground is treated, 1 st-order Bordeaux mixture (the proportion of copper sulfate, lime and water is 1: 100) is poured on the planting ground in general;
and step 9: harvesting in due time: the maturity during harvesting has important influence on the storage life and quality of the kiwi fruits, and the quality and flavor of the kiwi fruits are influenced if the kiwi fruits are harvested too early or too late; generally, when the soluble solid content of the fruits is 6-7%, the harvesting is in due date, the fruits which need to be stored for a long time are required to reach 7-10%, when harvesting, the fruits need to be lightly harvested and lightly placed, carefully shipped to avoid bruising and stacking, the fruits are preferably packed and warehoused along with harvesting and grading, the bottoms of containers such as boxes and baskets for containing the fruits are made of soft materials and are used as pads, the fruits are lightly harvested and lightly placed, the fruit bases cannot be pulled to damage the fruits, the fruit peels cannot be scratched, the fruits after primary harvesting are hard and astringent, the fruits need to be cooked and softened after 7-10 days to be eaten, the fruits after secondary harvesting are not suitable for storage, and the fruits need to be sold in time.
Furthermore, since the coconut coir in step 1 contains a large amount of salt, in order to avoid the influence of the coconut coir on the final pH value of the coconut coir substrate, EC of the coconut coir substrate needs to be determined before use, and if EC is higher than 1.0, calcium ammonium nitrate is used for salt washing.
